In 1726 a report very detailed local authorities attaches to Aggius the role of leader country in the illegal traffic of cereals. On the slope of the popular, however, the figure of the bandit was often equated with that of the underdog, fell into disgrace for reasons of honor and therefore worthy of respect and protection.

A case was dedicated to the local Bandit Sebastiano Tansu, "Il Muto di Gallura", figure that inspired the novel by Enrico Costa.
